A shiny module to synchronise datasets

The purpose of this module is to merge changes made to a subset of the data with the master copy of the data.

Usage

dataSyncUI(id)

dataSyncServer(
  id,
  data = reactive(NULL),
  data_subset = reactive(NULL),
  rows = reactive(NULL),
  columns = reactive(NULL),
  hide = FALSE,
  hover_text = NULL,
  auto = FALSE
)

Arguments

id: unique identifier for the module to prevent namespace clashes when making multiple calls to this shiny module.
data: master copy of the data.
data_subset: subset of data with altered entries.
rows: the row indices of data_subset within data.
columns: the column indices of data_subset within data.
hide: logical indicating whether the data synchronisation user interface should be hidden from the user, set to FALSE by default.
hover_text: text to display on download button when user hovers cursor over button, set to NULL by default to turn off hover text.
auto: logical indicating whether data synchronisation should happen automatically whenever data_subset changes. When TRUE, the sync button is not required. Set to FALSE by default for backward compatibility.
